Bolting an LLM onto a Next.js app is easy to demo and easy to get wrong. Here's the shape of a streaming chat feature that survives contact with real users — plus the rate-limiting, error, and cost details the tutorials skip.
Next.js 16 is less about flashy new APIs and more about the framework growing up: a faster default bundler, a clearer caching story, and some deliberate renames that make the mental model honest. Here's what actually matters when you upgrade.
The App Router makes every component a Server Component by default, and 'use client' opts into the browser. Getting the boundary right is the single biggest lever you have over bundle size and interactivity — here's how to reason about it.
